The gold-standard (heh, funny, because they love to talk up how a gold medal at tokyo was won on them) is the Farsports F1 handlebar:

I have a friend who recently bought a Kocevlo handlebar and I quite liked the design, as well as it's availability in a wide range of sizes
Bars I've bought:
Currently using bars that came with my SEKA exceed. I like that I was able to spec them as a 380mm/130mm. Weight is around 380g as well. Workmanship is beautiful. A bit flexy for my taste and I think the stem handlebar could be wider for easier cable routing and weight saving. The premium you pay largely goes to the beautiful finish, which is visible carbon under clearcoat. Apparently many people in China are buying these and putting them on western bikes.
I gifted my dad a Factor knock-off bar from yiqunsporttrade store, and he absolutely loves it, although they have some really terrible reviews for shipping times.
In 2019 I bought a Vision Metron 5D knock-off from Shop1916382 Store. Solid bars, still on the bike since I put them on! I mainly bought them because they were the narrowest integrated bars I could find at the time. That store seems to have gone inactive since then though.
That same year, I had bought a set of Madone knock-offs from TOSEEK, although these didn't have "true" cable integration. I didn't get to ride them very long because I wrecked them in a horrific crash just a few months later, but I liked them well enough! TOSEEK is a brand that sells a ton of handlebars, I have a mountain bike bar from them I like as well. I would say they are a great cheap name-brand so check them out too.
